Abstract
A process of making a drag-reducing aerodynamic vehicle system includes injection molding a body configured for attachment to a roof of a vehicle with a sliding core, wherein the body comprises an air inlet extending through a surface of the body, wherein the air inlet includes an air guide boss extending from an interior surface of the body, wherein the air guide boss adjusts an air stagnation point away from the windshield to reduce air pressure and drag on the vehicle; and ejecting the drag-reducing aerodynamic vehicle system from the injection mold using the sliding core.
Claims18
A drag-reducing aerodynamic vehicle system, comprising:
- a central fairing extending from a roof of a vehicle;
- and
- side fairings disposed on either exterior end surface of the central fairing, wherein the side fairings comprise airflow guide vanes protruding from an interior surface of the side fairings and wherein the airflow guide vanes attach to an exterior end surface of the central fairing;
- wherein air flows through the airflow guide vanes and is directed toward a rear of the vehicle to reduce air stagnation around the vehicle and accelerates air flow between the vehicle and a trailer attached to the vehicle to prevent air recirculation to reduce air pressure and drag on the vehicle.
A process of making a drag-reducing aerodynamic vehicle system, comprising a body attached to a roof of a vehicle, wherein the body comprises an air inlet including slits in the body, wherein the slits are disposed laterally to one another on opposing sides of a bisection of the vehicle and wherein the slits extend a length all or part of the way from a top of the body to a bottom of the body;
- wherein the air inlet includes an air guide boss extending from an interior surface of the body;
- and
- wherein the air entering the air inlet exits through an outlet and moves toward a side and rear of the vehicle, thereby reducing the drag experienced by the vehicle and wherein the air guide boss adjusts an air stagnation point away from a windshield and accelerates air flow between the vehicle and a trailer attached to the vehicle to prevent air recirculation to reduce air pressure and drag on the vehicle, wherein the method comprises:
- injection molding in an injection mold a body configured for attachment to a roof of a vehicle with a sliding core, wherein the body comprises an air inlet extending through a surface of the body, wherein the air inlet includes an air guide boss extending from an interior surface of the body, wherein the air guide boss adjusts an air stagnation point away from a windshield to reduce air pressure and drag on the vehicle;
- and
- ejecting the drag-reducing aerodynamic vehicle system from the injection mold using the sliding core.
A drag-reducing aerodynamic vehicle system, comprising:
- a frontal member in physical communication with a rear member, wherein the frontal member and the rear member extend from a roof of a vehicle, wherein the frontal member comprises fin boxes having airflow guide vanes disposed perpendicularly between sidewalls of the fin boxes;
- wherein air flows through the airflow guide vanes and is directed toward a rear of the vehicle to reduce air stagnation around the vehicle;
- and
- wherein the air flow guide vanes accelerate air flow between the vehicle and a trailer attached to the vehicle to prevent air circulation and reduce drag on the vehicle.
